HAIR-STBAIGHTENING, coMBQ I Hair-Straightening Combs, of which thefollowing is a specification.

This inventionrelates to hair flattening or straightening devices inwhich a bar or backing having a deeply serrated or toothed edge is usedand adapted to be heated and to have the combed hair taken in suitablequantities or swaths along the head of a person and drawn taut as itwill stand the pull over the said bar or backing and thereby relieved ofits natural or other tendency to undesirably kink or curl, and the primeobject of the invention herein is to provide a longitudinal bar orbacking of forged steel or the like having along one edge an integralseries of parallel deep teeth that are preferably slightly convexed ontheir outer edges and likewise concaved on their inner edges, such barhaving a rectangular cross-section and its inner end extended into atang whereby it is secured in place in a wooden or other non-conductorhandle for due manipulation in the kinky or curly hair or discomfort tothe person during the treatment.

In the accompanying sheet of drawings,

Figure 1 is a perspective view of the device embodying my invention inits most approved form, and Figure 2 is a transverse sectiontaken on thedotted-line 2, 2 of Fig-.

ure 1.

3 indicates the main head-bar or bodyportion of the. device, ofrectangular crosssection, and having along one side thereof.

a series of integral, parallel'teeth 4 whose outer faces 5 aresomewhatcurved or convexed starting from a point 5 at the outer loweredge of the bar 3 and terminating. at the tip 5", and whose inner faces6 slightly curve inwardly from said tip to a point 6 V Specification ofLetters Patent.

and then take a more direct or decided curve I 6* till :the inner, loweredge of'said bar is reached; all as best shown in Figure 2 and whichstructure I find has been the most pract cable for the purpose namedherein. In Fig. 2 1t Wlll. be very plainly seen that the head-bar orbody-portion8 is of exactly square cross-section along the respectiveteeth pits, whterebylfourc'1 distinct .or decided corners or rec angu are es are resented to the kinky hair that is td be woiind around the saidhead-bar several times, or at least one full turn to attain the desireddegree of tension or friction thereon while the teeth are passingthroughsaid hair in the flattening and straightening operationhereinafter described.

7 1s a pointed tang formed integral with the inner end of the head-bar 3and inserted in a handle 8 of wood or other suitable nonconductingmaterial. ferrule 9 is'placed on the tang? at the inner end of thehandle.

The customary metal The head-bar, together with the integral 7 ture thatwill not burn or otherwise injureI- thehair or the scalp. Such materialis last ing and will not be easily bent or broken in handling. In theoperation ofthe device'the heated comb is set with its teeth inengagement with a swath of'the kinky or curly hair and p then turned onits longitudinal axis sothat said hairshall be wrapped or wound aroundthe head-bar tight enough to permit a draw? mg or pulling on the kinkyor curly hairs through the teeth butwith sufficient tension onthe fourcorners of the head-bar 3, along the lines of the respective teeth pits,to

stretch them straight along the said head v bar, the heat of the teethsomewhat drying the hair at the time and-the heat of the head-'- baralong its flat back-surfaces and angles be ng also suliiclent to makesuchstretching lasting and resultlng in the desired flattened conditionof the hair, entirely free jfrom kink. or curl, and to readily lie flat,as well as to comb flat with'theordinarycomb, as

the user wishes. It is preferred and desirable to use oil of a suitablenature and consistency on the hair before applying de-Q ,viceherein tomake itpliable as well as form a backing or supporting-surface for thespread-out hairs When separated and Wound thereover and in contact Withthe said square or rectangular corners for the required drawing thereonin the direct and resultant straightening or flattening operation Whilethe comb is in a properly heated state, and a Wooden or othersuitablenonconductor handle in which the" said tang is inserted for theproper holding and manipulation of the comb in heating same as Well asin its use on the head of the person in the said treatment of curlv orkinkv hair, subbar being of square cross-section With fourdecidedly-square corner-edges along the line of the respective teethpits and adapted to stantially as herein shown and described.
